Viagra (tadalafil) is an anti-impotence drug known to help men suffering from impotence with their erections making them last longer. The effects of Viagra are based on the following mechanism: the active ingredient this medicine contains blocks a specific enzyme in your body called PDE5. This enzyme is responsible for regulating the process of blood outflow. At the same time Viagra dilates blood vessels in the penis allowing for more blood inflow. The combination of these two effects make it possible for the patient to achieve a hard erection quickly and maintain it for longer than usual. The erection goes away once the patient achieves an orgasm (ejaculates). Side effects are unlikely, but still possible, while the benefits of using Viagra are obvious to millions of people all over the world.
Side effects of Viagra
In some cases patients using generic Viagra online report a few side effects such as stuffy nose, backache, headache, and muscle ache. These side effects are mild and tend to disappear on their own without any need for your health care provider to recommend anything. More serious side effects need to be reported as soon as possible as they pose threat to your health and well being, not to mention that the success of your treatment may be affected. The following serious side effects are important to report as soon as you notice them: fainting, chest pain, lightheadedness, dizziness, shortness of breath, itching or burning during urination, blurred vision, loss of hearing, priapism, sudden severe loss of vision, rash, and ringing in ears. Sudden vision loss is one of most serious side effects of Viagra that may have to do with reduced blood flow to the optic nerve of the eye. Although it is not know for sure whether Viagra causes this rare side effect, or becomes one of factors, it’s recommended to tell your health care provider about any possible risk factors you have to avoid this side effect.
Things to discuss with the doctor before using Viagra
It’s important to talk to a qualified health care professional before you start taking Viagra, as there may be some contraindications in your case. Tell your doctor if you have any of the following medical problems that may require a dose adjustment or careful monitoring of your condition: diabetes, stomach ulcer, heart attack, high cholesterol, kidney disease, blood cell problems, stroke, conditions affecting the shape of the penis, liver disease, heart disease, bleeding disorder, high or low blood pressure, chest pain, pulmonary veno-occlusive disease, irregular heartbeat, or blood circulation problems. You also need to remember that Viagra is not supposed to be combined with any other drugs unless your health care provider told you it’s okay. While combining Viagra with such medicines as enoxacin, bosentan, antibiotics, antifungals, heart or blood pressure medications, HIV/AIDS medicines, imatinib, cimetidine, conivaptan, diclofenac, isoniazid, rifampin, or antidepressants can make your treatment less efficient, taking it along with isosorbide mononitrate, nitrates or isosorbide dinitrate can be quite dangerous and lead to a sudden drop in blood pressure resulting in a stroke or a heart attack.
You will need to watch for any alarming signs when you star using Viagra, especially if there are any contraindications that you have. DO not have sex and take Viagra if your health care provider told you to abstain from sexual activity, as this may be too much strain for your heart. If you experience dizziness, chest pain, tingling or numbness in your arms, chest or neck when having sex, stop the activity and consult your health care provider. Do not share Viagra with other people to whom it was not prescribed, as they may have contraindications you are not aware of.
